Original Summary

Two weeks ago I launched SongFlip (Android & iOS) to fix a daily frustration: clicking a music link sent by a friend, only to hit a browser detour or a streaming app you don't use. SongFlip runs silently in the background: set it up once, and whenever you tap a music link (Spotify, Apple Music, YouTube Music, Deezer, Tidal, Amazon Music, SoundCloud, Shazam), it intercepts and starts playback directly in your target player. Key metrics after 14 days: 1,000+ installs across platforms (maintaining a 5.0 ⭐ rating from 22 Play Store reviews) 10,834 unique tracks matched and cached in Firestore (L2 cache) $95 in revenue from Pro unlocks (universal playlist converter & smart web shares) 26,000+ background redirection events handled Top countries : US (26%), Mexico (11%), Spain (6%), India (6%), Germany (4%) Biggest technical takeaway : Server-side multi-tier caching was critical. Dynamic metadata resolution across 8 APIs takes 600–900ms, but cached hits respond in <90ms, keeping the redirection imperceptible to the user. Happy to answer questions about background link interception, mobile launch distribution, or store optimization!
